Orders placed after 2.00pm on the 28th December will be despatched when we re-open on Tuesday 2nd January. Orders placed after this will be despatched on Thursday 28th December. 1 pixel 268 MHz) requires additional circuitry in the adapter.The last order date/time prior to our Christmas Break is 1.30pm Friday 22nd December. HDMI is single link but allows for pixel clocks up to 340 MHz (HDMI 1.3 or greater). Anything faster for DVI such as 2560x1600 60Hz requires dual link DVI which these HDMI adapters do not support. 2560x1600 35Hz works because it's slow enough for single link DVI (pixel clock is less than 165 MHz). Note that the adapters listed are single link only even though they may say dual link DVI. Use 35Hz instead.įor information, I have a Dell laptop with NVIDIA Optimus ( GTX 525M and Intel GMA 3000 at the same time ) and a Dell U3011 monitor. Some users report that using 60Hz work fine at first, but crashes at restart. It will display a "we take no responsability for this !" warning, btw. If like me you can't get a higher res that 1080p, this is most likely due to the HDMI component of the motherboard but there is a neat workaround for this : simply go in the drivers settings, and create a new custom resolution.Īt least NVIDIA has such an option I don't know about AMD. And a female HDMI to female HDMI adapter. Such adapters really work (tested yesterday), but of course you need a dual-DVI-D cable. It's usually provided with new laptops anyway, I didn't even have to buy one.

That's the reason why you should prefer single-link-plugs for cables capable of only Seller that claim or or similarĭelock tripple-shield High Speed HDMI with Ethernet-cable: Many manufacturers claim "DVI-D-DualLink-Plug (25pins)" which means the Plug has 25 pins (19 pins for Single-Link-Connection and 6 dead pins that you can't mount it into a single-link-port). Difference between DualLink-Plug and DualLink-Connection Passive Adapters and Cables can't handle DualLink-DataconnectionĪcccording to Wikipedia: HDMI (19pins) is compatible with DVI-D-SingleLink (19pins) without conversion.Īs written by vojtech: A DVI-D-DualLink ( max would need an active converter with power-supply. String all three together, make sure all are powered up via their USB connectors and voilà, beautiful full resolution 2560x1600 picture at 60 Hz refresh rate on my Dual Link DVI monitor. This works for Linux, on Windows you may not need the EDID change, or you may need a more extensive one. A proper solution would be to provide a modified EDID file directly to the driver. I solved that by adding a S/PDIF audio de-embbedder for HDMI that I got off eBay into the chain that adds the CEA EB to add audio descriptors to EDID. Obviously, a pure DVI monitor will not have a HDMI VSDB in CEA EB of EDID. The reason was that the Linux Radeon driver would enable pixel clocks above 165 MHz only in case a monitor has a HDMI Vendor Specific Data Block in the Consumer Electronic Association extended block of EDID. However, the Linux Radeon driver (xf86-video-ati) was still not happy with it, and ignored the 2560x1600 videomode in the list of valid modes in EDID. In case your monitor takes a DP input at full resolution, using only this adapter is enough - no need to convert to DVI-DL.Ĭonnecting those two together should provide a HDMI 1.4 to Dual-Link-DVI solution. Several brands sell adapters based on this chip. There were no solutions for this until recently, when the STMicroelectronics chip STDP2600 became available. With that, we've reduced the problem to converting HDMI 1.4 to DisplayPort 1.1. And the only one that's widely available is a DisplayPort to Dual Link DVI adapter, sold under several different brands. ![]() You need a device that generates Dual Link DVI output from a single link input. ![]() All adapters that you'll find are passive single-link adapters, even though they may be advertised as dual-link.Īlthough a HDMI 1.4 to Dual Link DVI adapter is possible to implement using an Analog Devices ADV7619 297 MHz HDMI 1.4 receiver that does automatically split high pixel clock links into odd and even pixels and two ADV7513 165 MHz HDMI 1.4 transmitters to transmit the pixels over two separate links, no manufacturer is making such a device. ![]() Stop searching for HDMI to DVI-DL adapters. I'm writing this on a 2560x1600 Dual Link DVI monitor connected to a computer using HDMI 1.4.
